XOOPS模組開發
=========

1. 先編輯樣板，根據身份加入「編輯」按鈕 ```
    
    <td>
      <{if $isAdmin}>
        <a href="admin/main.php?action_id=<{$action.action_id}>" class="btn btn-warning btn-xs">編輯</a>
      <{/if}>
      <a href="index.php?action_id=<{$action.action_id}>" class="btn btn-info btn-xs">詳情</a>
    </td>
    ```
2. 接著編輯 admin/main.php，修改一下其流程，因為有傳入 action\_id 的變數進去，表示要修改該資料內容了。
    
     ```
    
    /*-----------執行動作判斷區----------*/
    include_once $GLOBALS['xoops']->path('/modules/system/include/functions.php');
    $op        = system_CleanVars($_REQUEST, 'op', '', 'string');
    $action_id = system_CleanVars($_REQUEST, 'action_id', 0, 'int');
    try
    {
        switch ($op) {
    
            case "insert_action":
                $action_id = insert_action();
                header("location: ../index.php?action_id={$action_id}");
                exit;
    
            default:
                action_form($action_id);
                break;
        }
    } catch (exception $e) {
        redirect_header($_SERVER['PHP_SELF'], 3, $e->getMessage());
        // $xoopsTpl->assign('error', $e->getMessage());
    }
    include_once 'footer.php';
    ```
3. 最重要的是修改原來的表單函數，針對編輯狀態要多加一些動作：
    
     ```
    
    //顯示預設頁面內容
    function action_form($action_id = '')
    {
    
        global $xoopsTpl, $xoopsDB;
    
        include_once XOOPS_ROOT_PATH . "/class/xoopsformloader.php";
        if ($action_id) {
            $tbl    = $xoopsDB->prefix('actions');
            $sql    = "SELECT * FROM `{$tbl}` WHERE `action_id` ='{$action_id}'";
            $result = $xoopsDB->query($sql) or web_error($sql);
            $val    = $xoopsDB->fetchArray($result);
            $op     = 'update_action';
        } else {
            $val = ['title' => '', 'action_date' => date('Y-m-d'), 'end_date' => date('Y-m-d 17:30:00'), 'enable' => '1', 'content' => ''];
            $op  = 'insert_action';
        }
    
        $form = new XoopsThemeForm('編輯活動', 'name', 'main.php', 'post', true);
        $form->addElement(new XoopsFormText('活動名稱', 'title', 40, 255, $val['title']), true);
    
        include_once XOOPS_ROOT_PATH . "/modules/tadtools/cal.php";
        $cal = new My97DatePicker();
        $cal->render();
        $action_date = new XoopsFormText('活動日期', 'action_date', 15, 255, $val['action_date']);
        $action_date->setExtra("onClick=\"WdatePicker()\"");
        $form->addElement($action_date, true);
    
        $end_date = new XoopsFormText('截止日期', 'end_date', 15, 255, $val['end_date']);
        $end_date->setExtra("onClick=\"WdatePicker({dateFmt:'yyyy-MM-dd HH:mm:ss', startDate:'%y-%M-%d 17:30:00'})\"");
        $form->addElement($end_date, true);
    
        $form->addElement(new XoopsFormRadioYN('使否啟用', 'enable', $val['enable']));
    
        include_once XOOPS_ROOT_PATH . "/modules/tadtools/ck.php";
        $ck = new CKEditor("tad_signup", "content", $val['content']);
        $ck->setHeight(350);
        $editor = $ck->render();
        $form->addElement(new XoopsFormLabel('活動內容', $editor));
    
        $form->addElement(new XoopsFormHidden('op', $op));
        $form->addElement(new XoopsFormHidden('action_id', $action_id));
        $Tray = new XoopsFormElementTray('', ' ', 'name');
        $Tray->addElement(new XoopsFormButton('', 'name', '清除', 'reset'));
        $Tray->addElement(new XoopsFormButton('', 'name', '送出', 'submit'));
        $form->addElement($Tray);
        $action_form = $form->render();
    
        $xoopsTpl->assign('action_form', $action_form);
    }
    ```
